The discovery of radioactivity also had another side effect, although it was several more decades before its additional significance to geology became apparent and the techniques became refined. The age of a particular sample, and a particular geological time scale, only represents the current understanding, and science is a process of refinement of that understanding.
The possible confounding effects of contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created. Dinosaurs were found after the first occurrence of land plants, insects, and amphibians.
